Uhd will require some machine muscle, post a speccy and let's see what you have.

My Windows 7 Media Play won't play UHD videos.
At first I thought I found out the reason, and that is Windows 7 does not support UHD videos. I was looking to find a program to solve this.
Today I heard something different from my computer repair shop. I was told the problem was with my computer: the processor and the video card. I was told the processor is not capable of working on such big files. As with the video card problem, I did not recall what I was told - it was something I did not understand at the time.
I was told nothing can be done; no upgrades can be done. The only way to solve is to buy a Window 10.
I tried to play those videos with my Photoshop CS6. They did play but very choppy and was like slow motion. I wasn't even sure if some of the movements had been missing.
I will not opt to convert the videos to a lower resolution so I can play it. I especially need UHD resolution to view detailed colors of the videos so I can selectively make still images.
I do not know if there is anything at all that will help in order to avoid purchase two new computers. My Windows 7's work just fine if not for this problem.
